CONNECTOR.

Specification of Letters Patent.

To all whom 'it may concern:

Bc it known that'I, CHARLES E. GonLEr, a citizen of the United States, and a resident of Detroit, in the county of Wayne and State of Michigan, have invented a new and Improved Connector, of which the following is a specification.

This invention relates to means for con* necting a plurality of series of electric circuits, and its object is to provide a device of this type especially adapted to connect 'ecdwires to the bodies of electric lamps which are supplied with a plurality of lighting filaments.

Large numbers of electric lamps of the lheadlight, type are at present being'manu factured with two electric light filaments, usually oi different candle power, mounted in either one or two bulbs, the filament of higher candle power being placed at the focal center of the reflector, so that its rays will be projected in parallel lines, and that of lower candle power being placed away from and preferably above the focal center, so that its rays will be projected divergently, so that a mild diffused VAlight will issue from the lens, which light will not be blinding to pedestrians. The first filament' is especially adapted for country and the second for city driving.

This invention consists of ar normally fixed sleeve of metal of novel design having a pair of novel binding posts, together with a novel plug of insulating material having means to receive-three wires, one for each i of the binding posts and the third for the metal sleeve.

In the accompanying drawing, Figure 1, is an elevation ot' this improved connector mounted in the body of an electric head ligl'it. Fig. 2 is an elevation of the other side'. Y Fig. 3 is a central longitudinal section of this connector. Fig. 4 is a similar section at right angles to the section of Fig. 3. Fig. 5 is a section on the line-5-'5 of Fig. 3.

Similar reference characters refer to like parts throughout the several views. Y

The .lamp body 1, reflector 2 and lensB, shown in thc drawings may be of any desired construction. In the reflector isa sleeve 4 to receive the socket 5 of a light bulb having a high power filament whose heated portion 7 is at the -focal center of the relcctor, and ay low power filament whose heated portion 8 is at one side, preferably above the focal center. 4One wire 9 to the lngh power ilament connects to the circuit l0, andjone wire 11 of the low power lilament connects t0 the circuit 12.' The wires 13 and-14 of these filaments may be grounded on the sleeve y4, or wherever else desired. It will be understood that it is not necessary to have' both filaments in one bulb, manylanips being provided with two independent bulbs, each having one wire from the filament grounded on the reflector. A sleeve 16 is shown connected into the vbody and is'therefore grounded. In this sleeve is removably secured the metal cylindrical shell 17, by means of the screw 18. Within the shell is a cylinder 19 of insulating material such las hard rubber or indurated fiber,` having a central tongue 20 that separates the binding posts 22. These posts have rectangular outer ends 23 provided with holes 24 to receive the circuit wires within the lamp body', and with the screws 25 to, hold the wires 10 and l2.

On the 'outer ends of the posts are heads 26, and on the. posts are the springs 27 which force the posts outwardly. The shell is formed with 'notches 28 and 29, a tongue 30 .projecting into one ot' the notches as shown in Fig. l. The shell and the parts mounted therein constitute the female member of the connector.

. The male member of the connector is a `plugvor cylinder 33 of insulating material,

having a circumferential collar 34, and vlongitudin'al passages in which are seated the metalA bars 35, 36 and 37. The outer end of this cylinder may be threaded to receive a cap 38,v also of yinsulating material. The bars are all-formed with sockets 39 to receive the wires 40, 41 and 42, theA screws 43 securing the wires in position. The ends of the bars 36 and37 are flush with or protrude slightly from the end of the member 33 and engage the ends of the posts 22. The third bar. 35 cuts through the cylindrical surface of vthe plug 33 and is cut down to form a continuous surface therewith', as shown 1n Figs.

B' and 5. A pin 45 is shown extending envtirely through this bar and the plug, its-ends projecting about the thickness of the shell, 17 A second pin 46 also projects 'from the bar. The wire 42 may lead to a contact 4T and the wire 41 to a contact 48, while the wire 40 leads to a currentsource 50, which is sleeve 16, alter Which the lamp is ready for .the plug from turning.

shipment.l After being mounted on the ve hicle or 'Wherever else it is to be used, the proper wires 40, 41 and 42 are connected vto the plug 33. This plug is then inserted in the shell 17 with the tWo pins l5 and 46 passing into the notch 28, until the ends of'the bars 36 and 37 press the posts 22 outwardly, after which the plug is turned 'to carry the ends of the pin 45 into the downturned ends of the notches 28 and 29, as shown in Figs.v l and 2. The springs 27 will hold this pin in these downturned ends and thus prevent the plug being locked in the when this pin is in the notch 28. The pin 45 insures a good connection. between the shell and the bar 35, that is, between the body of the lamp and the Wire 40.

I claim:

l. In a connector for electric Wires the combination of a female member consisting of a metal shell, a core of insulating mat-erial, a binding post slidably mounted in the core, and a spring to normally hold the post inwardly; and a male member fitting Within The pin 46 prevents f shell exceptv the-shell and consisting oi. a body of insulating material, a plurality of posts mounted in the body, each formed to receive the end of' a wire, one of the posts contacting with the shell and the' other contacting end .to end with thexbirtding post; and means to secure `the meinbertltpgether.

2. In a connector for electric Wires, the combination 'of a female member consisting of a metal -shell adapted to connect into an electric circuit, a' core of insulating material Within the shell, 'a pair of binding posts slidably mounted in the core, and springs on said-v posts; land a male member iitting within the shell-and consisting of a cylinder of insulating material, a series of posts mounted in `said cylinder, each'ormed to receive an end of a Wire, one of the posts contacting with the shell and the other two contacting with the adjacent. ends of the spring pressed,

posts; said shell formed'with notches, and a pin carried by the cylindrical male member adapted to engage in the notches to secure the members together.

. In testimony whereof I have signed this specification in the presence of two subscribing Witnesses. i
